How Charities Can Use AI for Fundraising Optimisation

AI is helping charities raise more with less. From donor segmentation to grant writing, this guide covers practical ways your organisation can use AI to strengthen fundraising performance without needing a dedicated tech team.

As recently featured in The Jewish Chronicle, Hartz AI has been working with organisations including the Board of Deputies, the United Synagogue and the Association of Jewish Refugees to bring practical AI solutions to the charity and community sector.

AI can help charities improve donor targeting, write stronger grant applications, analyse campaign performance and personalise supporter communications. Most tools are free to start and do not require technical skills.

AI-Powered Donor Segmentation

The most impactful way charities can use AI is to understand their supporters better. AI-powered donor segmentation analyses giving patterns, engagement history and demographic data to identify which supporters are most likely to give, upgrade or lapse.

Instead of sending the same appeal to every supporter, AI helps you tailor your message to each segment. Major gift prospects receive a different approach from regular givers, and lapsed donors get re-engagement campaigns designed around their previous interests.

Practical Steps to Get Started

  • Export your donor data: Pull giving history, event attendance and email engagement from your CRM or spreadsheet.
  • Identify natural segments: Use AI to cluster supporters by behaviour, not just donation amount. Look for patterns in frequency, channel preference and cause affinity.
  • Personalise your next appeal: Write three versions of your next campaign email, each tailored to a different segment. AI can draft these variations in minutes.

Organisations like the Board of Deputies have used data-driven engagement analysis to better understand community sentiment and tailor their communications accordingly. The same principles apply to fundraising: better data leads to better conversations with donors.

Campaign Performance Analysis

Most charities run campaigns and hope for the best. AI changes that by providing real-time insights into what is working, what is not, and where to focus next. Campaign performance analysis with AI goes beyond open rates and click-throughs to reveal deeper patterns.

AI can analyse which subject lines drive the most donations, which channels deliver the best return, and which time of day your supporters are most responsive. Over time, these insights compound: each campaign performs better than the last because you are learning from real data, not guesswork.

Event Fundraising Analytics

Charity events are a major fundraising channel, but measuring their true ROI is often difficult. AI can track the full donor journey from event registration through to post-event giving, helping you understand which events convert attendees into long-term supporters.

For charities exploring AI adoption, starting with campaign analytics is often the quickest win. You already have the data; AI just helps you read it faster and act on it sooner.

AI-Assisted Grant Writing and Applications

Grant applications are time-consuming and competitive. AI can significantly reduce the drafting burden while helping you produce stronger, more compelling submissions. This is not about replacing human storytelling but about accelerating the process.

AI tools can draft initial sections based on your impact data, summarise annual reports into concise narratives, check applications against funder criteria, and even suggest improvements to your case for support. Based on our experience with clients, AI can cut grant writing time by up to 60% while producing higher-quality applications.

Beyond Grant Writing: AI for Impact Reporting

The same AI capabilities that help with grant applications also strengthen impact reporting. AI can analyse programme data to identify trends, generate visualisations for trustees and funders, and draft narrative reports that connect numbers to stories.

If your charity is ready to explore AI for fundraising and operations, AI training for your team can help staff get confident with these tools quickly. For a tailored approach to your organisation's needs, explore our AI consultancy services.
